CONCFAINER AND CLOSURE CONNEQTION.

Application file'd May 6, 1921. Serial No. 467,324. Renewed April 14, 1926.

This invention relates to means for per- .manently attaching a closure member to attachment of the member in, or its removal from, its functioning position.

In order to prevent the n iisplacenient and loss of removable cover members such, for instance, as the relatively small screw caps used in connection with collapsible container.

tubes, caps have heretofore been secured to the tubes by means of sections of wire attached at one end to an eye on the tube and at the other end looped around the periphery of the cap. This construction has been unsatisfactory in practice because of the interference of the connecting wire with the fitting of the cap to the threaded nozzle of the tube and-with the rotation of the cap while in engagement with the threads.

It is an object of this invention to pro-' screw cap can be obviated by making use of a flexible retainin member having one end attached to the fiody of the tube and the other end attached to the outer end of the screw cap substantially in alignment with the axis of rotation-thereof. vThis arand showing still another form of retainrangement not only leaves the peripheral margins of the cap wholly. free for engagement by the fingers. of the-user, but any force that may be exerted on the flexible connector is in the-form of a harmless twist or rotation instead of an objectionable pulling or tugging strain.

Another feature of the invention resides in the simple and effective means em loyed for attaching the ends of the flexib e connecting member to the tube and to the cap member. This feature includes recesses or pockets formed in the tube and thecap in the same operation in which the arts-are themselves produced, the recesses eing arranged to receive enlargements formed on the ends of the flexible connector. The en- 'larged ends of the connector are held in place in the recesses preferably by upsetting the edge or otherwise restricting the an object while permitting the unrestricted size of the entrance end of eachrcc'ess after 1 the ends of the connector have been placed in the pockets. 1 The flexible connector ina preferred form of the invention consists of a length of metal chain of a well-known type in which the links have universal joint connections with each other, so that an unrestricted turning H movement of the cap to which one en d'of the flexible connector is attached is permitted. the flexible connector may take the form of a member in which a suificient torsion or twist may be produced to effect the required rotation of the cap member. Preferably the flexible connector has a length such that it may be used as a means for suspending the container'from aholder. i In the drawing: Figure 1 is a side view of the discharge end of a collapsible tube container equipped preferred form of the invention;

F'gure 2 1s a sectional view of the de-.

viceshown in Figure 1; Figure ,3 is an end shown in Figure 1 looking to the right;

Figure 4 is an end view of a cap for the container before the retainer member is attached thereto;

Figure 5 is a view in cross section of the cap shown in Figure 4;

Figure 6 is a view similar to Figure 2 showing a mod'iiied form of cover-retaining device; 7 v

Figure 7 is, a view similar to Figure 6 ing device.

Referring to the drawings, there is shown a portion of a collapsible-tube container 1 having an ordinary form of threaded discharge spout 2 which is adapted to be closed by means of the screw cap cover 3.

In order to provide for attaching the cap member 3 to the tube in such manner that misplacement or loss of the cap is prevented, a flexible connecting member 4 is provided In another form of the invention with a cover retaining device embodying a view of the device which is attached at its ends to the cap-3 and to a point in "the shoulder 5 of the tube 1-. Preferably the connecting member 4 takes the form of a well known type of chain commonly used with pull-chain electric lamp sockets and which can bevfreely twistedor rotated by reason of a form of universal joint connection between the links. Provision is madefor attaching the flexi ble connector to therap member 3 by producing a recess or pocket 6 in the cap, prefshoulder 5 of the tube, the end ol? the chain 4 is placed in the pocket, and the entrance edges of the pocket 8 are turned inwardly to permanently enclose the terminal ball of the chain in the pocket. It will be seen that .a retaining device for the cap 2:3 ol the, collapsible tube 1 is thus provided which will permit of the rotation of the cap in relation to the threaded spout 2 of the container, and

that the length of the flexible connector 4 is such as to provide a convenient meansoi suspension of the entire container froi-n a hook or similar support.

In Figure 6 of'the drawing a similar result is obtained by means of a flexible connecting member 9 formed preferably of a short length of wire having enlarged end members 10 which can be conveniently anchored in the-corresponding pockets 6 and 8 in the cap 3 and tube shoulder 5, as in the form of the invention already described. The length of wire 9 either single or stranded permitsofsuflicient torsion or twist to provide for the necessary rotation of the cap member 3.

In Figure 7 of the drawing still another form of connector is'shown as taking the form of a simple helically coiled w'ire havm its opposite ends anchored in the pockets 6 and 8. -With this form of connector enlarged end members are dispensed with and the entrance ends of the pockets are up- 1.,ln combination with a container having a rotatable cover the outer end of which is provided with a pocket, a flexible connector ha ring one, end attached to the container, the other end of said connector being eu-- larged and seated in. the pocket in said cover,

and the entrance of said pocket being upset to anchor said enlarged end of said connector in said 'pocket.

2. In combination with a collapsible tube container fhavinc a screw cap cover. a flexible, connector having; one end attached to the endtot'said screw cap cover, the other end of said connector being enlarged, the 65 shculdercf said container beinc provided with a pocket to receive the enlarged end of said connector, and the entrance o't said pocket being upset. toanchor said enlarged end of said connector in said pocket.

3. In a device of the class described, a coin tainer having a threaded neck portion formed thereon. and also havinga closedbottomed socket formed on the exterior thereof adjacent the neck portion, a screw cap for the container also provided with a socket, a flexible connection, and members I carried at the ends of the connection and held, respectively, in the sockets of the cap and container. I

4. In a device of the class described, a container having a threaded neck portion formed thereon, and also having a closedbottomed socket formed on the exterior thereof adjacent the neck portion, a screw .cap for the container also provided exteriorly thereof with a closed-bottomed socket,

a flexible connection, and members carried at the ends of the connection and held, respectively, in the sockets of the cap and container.

In testimony whereof I alfix my signature.
